Mirror switch assembly

Abstract

A mirror switch assembly that may be incorporated with a mirror unit for tilting a mirror. A set of contacts rotates when the mirror unit is rotated between a horizontal orientation and a vertical orientation. The set of contacts is electrically coupled to two motors and to a set of terminals. The set of terminals is electrically coupled to at least one mirror adjustment switch that is located in the interior of the vehicle. When the set of contacts rotate, the connections between the terminals and the motors are reconfigured to compensate for a change in orientation of the mirror.
